FOREWORD

Before you begin the installation of your supercharger locate the Computer Chip Voucher supplied in your information packet. The 2001 Mustang Cobra supercharger kit requires a computer chip upgrade. You must fill out the voucher and send or fax Paxton Automotive the 4 digit computer code. Most commonly, there will be a white tag attached to the passenger side door jam or the body of the cab. The code will consist of 3 letters, a dash, and 1 number (FXU-1, for example) with a bar code. If the sticker is not there, the code will be on the computer itself. The computer is located under the dash on the passenger’s side of the vehicle. The code tag will be visible without removing any interior panels.

Complete the Paxton Automotive/Ford Computer Chip Voucher and return it to Paxton Automotive to receive the proper computer module for your vehicle.

Important: Read through the chip installation instructions beginning on Page 17 to determine if you are able to complete the task. If not, please call Paxton Automotive at 1-(888)-9-PAXTON to obtain a Return Goods Authorization number. With this number, you can mail in your computer module for the modifications to be performed by Paxton Automotive in a timely manner

or translated into another language in any form, by any means without written permission

of Paxton Automotive.

INTRODUCTION

Congratulations! You have purchased the finest street supercharger available for the Mustang Cobra. The centerpiece of this kit is the High Efficiency PAXTON Supercharger, a mechanically driven centrifugal blower.

This kit comes with all the parts you will need to install the supercharger. The instruction manual has been edited in order of sequence, and photographs and drawings have been included to illustrate the text. This will allow you quick part identification and orientation.

The installation will require metric and SAE sockets and wrenches, a hand drill and bits, an Air Hammer (and compressor), a 3/8” x 18 NPT tap, screwdrivers, and a supply of buckets for the reserve of coolant and oils.

We suggest that you obtain a copy of a Mustang shop manual for your model of car. This may be obtained from your dealer, or may be ordered by mail from Helm Publications at (800) 782-4356. Become familiar with the details of your car’s system. If it is not operating within normal parameters, we do not recommend the installation or use of the supercharger.

For the quickest installation time, we suggest that you read this manual thoroughly before beginning. Make sure that you understand the process, have identified the areas of the car that you will be working on, and have the tools that you will need on hand. The average installation time is 8 to 10 hours, but your time will depend on your working conditions, experience installing superchargers, personal skill level, and preparedness for the job. This estimate does not include time for the initial vehicle inspection, cleaning, fine tuning, or trouble-shooting. Once again, we recommend reading the manual before beginning the process. We are available for tech support at (805) 604-1336, Monday through Friday, 7AM - 3 PM PST.

After reading the manual, verify that all major assembly groups are present in the main kit box. As you remove a box or bag, note the identification label and compare it to the parts list.

PAXTON AUTOMOTIVE makes every effort to insure that all parts

are included in the box. If you discover that you are

missing any part, or that a part was damaged in shipping,

call PAXTON immediately. DO NOT begin installation if a part is missing.

Failure to contact PAXTON prior to beginning installation

will result in a charge for the missing part.

We suggest that the engine compartment be cleaned before the installation. You can clean the engine with a pressure washer that is found at self-serve car washes. Use a safe-for-aluminum cleaner/degreaser, and cover the distributor and any electronics with a plastic bag to prevent water from entering.

You are undoubtedly eager to get started, but please take a little more time to insure that your safety is not in jeopardy. A moment’s lack of attention may cause a serious injury to you, or to someone else who happens to be standing around. By following some simple safety precautions, you can avoid many potential dangers. The following list is not meant to be a comprehensive list, but rather it is meant to make you aware of some of the risks, and encourage you to take a safety minded approach to your work area.

PAXTON Automotive thanks you for your purchase. We welcome your comments and suggestions to help us improve our product.

Never rely solely on a floor jack when

working underneath a vehicle. Always

use jack stands that are rated for the

weight of your vehicle, use them at the

recommended lift points, and place your

vehicle in “PARK” or “FIRST” gear with the

parking brake set.

Always use eye protection when using power

tools, such as drills, saws, and grinders, or

when working underneath a vehicle.

Never smoke, use an open flame, or have spark

producing items around gasoline or flammable

objects. Always have a fire extinguisher that

is rated for chemical and electrical fires handy

when working on motor vehicles. Also, make sure

that the extinguisher is fully charged.

Operate engines only in a well ventilated area. Carbon

Monoxide, gasoline, and solvent vapors

are colorless and sometimes odorless, and

may asphyxiate or explode without

warning.

Always disconnect the battery from

your engine before doing work on the electrical

or fuel systems, or doing underdash work.

The chemicals used in the vehicle systems,

such as oils and coolants, are poisonous. Clean

up any spills immediately, and dispose of

waste materials properly. Pets, wild animals, and

children may die if they ingest the liquid.

INSTALLATION

1. FUEL SYSTEM MODIFICATIONS

.............. .......*** NOTE ***

Beware of coolant spills. Mop up any spilled coolant immediately. Radiator coolant is very attractive to animals,, and highly poisonous.

A. Drain approximately one gallon of coolant

from the radiator and disconnect the negative side of the battery. Disconnect the MAF sensor, air inlet temp sensor and air idle bypass hose from the air inlet tube, then remove the inlet tube and air filter housing by removing the single 8mm bolt. (See Figs. 1-a, 1-b.)

Fig. 1-c

C. Unplug the idle air control (IAC motor har-

ness from the IAC, located on the left rear portion of the upper intake plenum. Unplug the two vacuum fittings (one on top of the plenum, one at the EGR valve) to the right of the IAC. (See Fig. 1-d.)

Fig. 1-a

B. Unplug the throttle position sensor harness,

located on the left side (the side closest to the firewall) of the throttle body. (See Fig. 1-b.)

D. Unplug the EGR sensor, located at the rear

most portion of the upper plenum. (See Fig. 1-e.)

Fig. 1-e

E. Using a 1-1/16" open end wrench, loosen the

EGR tube, located at the rear of the EGR valve. (See Fig. 1-f.)

G. Lift the upper plenum up, and disconnect the

two small vacuum hoses located at the rear of the plenum. Lay the plenum onto the driver’s side of the engine compartment. (See Fig. 1-h.)

Fig. 1-h

H. Relieve the pressure in the fuel rail by

depressing the small Schraeder Valve with a phillips head screwdriver. A small amount of fuel will come out of the valve, so have a clean rag ready. Remove the 10mm bolts (2 per side) that secure the fuel rails to the intake manifold. (See Fig. 1-i.)

Fig. 1-f

F. Remove the eight 8mm upper plenum bolts.

(See Fig. 1-g.)

Fig. 1-g

Fig. 1-i

I. Lift the rails up and remove the stock injectors

from the intake manifold. The injectors are sealed with O-rings and may be difficult to remove, but they will come out. Replace them with the supplied High Performance Injectors. (See Fig. 1-j.)

Fig. 1-j

10. Because you have replaced the stock injectors

with injectors having a different configuration, some modifications to the plugs are necessary. Attach the supplied injector plug pigtails to the stock connector. (See Fig. 1-k.)

Fig. 1-k

*** NOTE *** For maximum performance, PAXTON Automotive recommends the factory stock platinum spark plugs to be replaced with a copper spark plug gapped to .035. (Autolite 764, NGK TR5, or equivalent)
